PENClL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 453,448, dated June 2,1891.

Application filed January 29, 1891. Serial No. 379,508. (Ne model.)

To all whom it may concernz Be it known that I, OHARLEs H. REDMAN,

a citizen of the United States, residing at Newark, in the county ofEssex and State of New Jersey, have in'vented certain new and usefulInprovernents in Pencil-Sharpeners; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a partof this specification.

This invention is to provide a device of greater convenience and toenable the pencil to be slarpened with greater t'acility and ease; andit consists in the improved pencil` sharpener and in the arrangenentsand combinations of parts, substantally as will be hereinatter setfor-th, and finally enbodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters indicatecorresponding parts'in each of the figures, Figure 1 is a plan of thedevice and showing the pencil about Fig. 2 is a section taken on linenc, and Fig. 3 a section taken on line y.

In said drawings, a indicates a netal casting, of which d is 'afinger-piece, a a flat shank, b a conical sharpening-head, the aXialcenter of which is at rightangles to the longitudinal center of theshank and fingerpiece, and c a cutter-seat in the longitudinal line ofthe shan'k, but on opposite sides of the conical head in which thepencil is inserted when being sharpened.

g indicates a blade arranged on the seat and having its cutting-edgeexten'd to a slot g' in the conical head, so as tocut and sharpen thepencil h when inserted and turned in said head. The blade is held onsaid seat by a setscrew e', which allows 'of an adjustment of the bladewith reference to the slot, and also allows of a renoval ot' the bladefor sharpening.

f indicates a flat file for sharpening the lead, soldered on the shank,the latter being recessed, as shown, to receive the same. A

projecting stop c extends transversely across the shank to protect thefingers of the operator fron the lead when filing the pencil to apoint..

By holding the sharpener by the fingerpiece in the position shown inFig. l the wooden part of the pencil is first sharpened by the cutter,and then the lead, which is not allowed to engage the blade and dnll thesame, is filed to a point on the file of the shank. The flat shankinterposed between the lingerpiece and the conical head provides abearing for the flat file and enables the latter to be placed so thatthe cutting orlead-sharpening chisel-edges will lie parallel with theaxial center of the conical head. By this Construction the personsharpening will not have to change the angle of the pencil when changingfrom the wood-sharpening to the lead-sharpening Operations, as in caseswhere the file is arranged directly on the side of the conical head.

Having thus described the invention, what I claim as new is- 1. Thecombination, with the finger-piece, fiat shank, and conical head havinga slot and cutter, of a file arranged on said flat shank, thecutting-edges of which are parallel with the aXial center of the saidconical head, substantially as set forth.

2. In combination, a fiat shank having a finger-piece at one end and aconical cutterhead at the other, disposed with its axial center at rightangles to the said shank, and a file arranged on said shank,substantially as set forth. e i

3. In combination, a shank having a file on the face thereof, afinger-piece at one end thereof, a stop or ridge forned between the saidfile and finger-piece, and a cutter-head having a slot and bladearranged at the other end of said shank, substantially as set forth.

In testinony that I claim the foregoing I have hereunto set my hand this27th day of January, 1891. 4

CHARLES H. REDMAN.
